Cheerio, the runt cinny girl that Mike Cavanaugh has, started out so tiny it was pitiful. Most of us thought she would not survive.
But now ? She's a massive female who dwarfs her "normal" sibling. The thread about her is around here somewhere. I believe she was around 1600 grams at 15 months old ? Something like that.
So yes, they grow at very different rates. I have a pair of het pied girls, not related, they were within 100 grams of each other for months. Then suddenly, one stopped eating and the other jumped way ahead, then they reversed themselves. Finally they got their acts together and are only separated by around 300 grams or so again.
